Acoustics:
- Frequency response on axis, ref 1KHz: +/- 2dB 110Hz-20KHz
- LF Frequency response, ref 1KHz: -3dB @ 95Hz, -10dB @ 55Hz
- System damping is optimal @ Q = 0.707
Responses:

Frequency response of the SoundBucket. The response is exceptionally flat, and unlike other speakers, the bass response does not vary with user volume settings
